JOHN RAMBO –
This is the plug in solution for your toyota
So first off, I read alot of negative reviews on this wire harness and was skeptical to buy it, let me just say I’m glad I did. So the white insulator inside the h4 plugs that people complained about being loose is not a problem, it is how the plug is assembled and once plugged in it has no where to go and is tight and secure, and for people complaining about the wires being too small ? Well mine has 12g wire throughout and 10g wire for the main power and ground, which is way more than enough gerth to run 2 led headlights which is what this harness is designed for. And I’ve also read people complaining about the blue high beam indicator on their dash cluster not working after installing led headlight bulbs? Well mine did work and quit after installingthe led headlights also, the led headlight bulbs do not draw enough amps to trigger the factory relay (this harness made it work again), Last of all everything looks and feels and performs and is high quality on this harness, wires, loom, relays and all plugs are solid ð . The only thing I changed is the 2 ends that you ground at each headlight harness, I cut off the c loop connector and crimped/shrink tubed on a o loop connector, not necessary but for me I like the loop connectors better to go on a ground bolt vs. The c loop connector. All in all I rate this kit A+++ and ordering another one for my other toyota for doing led headlight conversion.
Well Thatâs Swell –
Works well
Works well on an old 1982 Starlet. Attached lights are super bright. Easy install and can be cleaned up for a good looking engine bay.

you do need this – 1996 Tacoma
This is utterly necessaryI bought LED headlights in housing for my 1996 Tacoma, they were listed as ‘PlugnPlay’ – They do function but not as both high and low beams just a singular setting with the other being off.This is because the 9004 (my) wiring does not supply a consistent connection to the positive battery terminal – what hibeam light needs in the 9007 replacement. Even though they could be plugged in they were internally wired for a 9007 setup -This harness makes them function as intended with 10 min of work. Literally easy as can be – I went from being sad over my new lights to feeling ecstatic just with this price and use effective harness.For the price point I thought it could be cheap quality – nope it is great. I wish the fuse wire for the positive terminal was a bit longer but this is minor – its worth it

Good old car upgrade
Got these to take the load off of My old trucks headlight switch. These are great for the longevity of older car wiring systems by taking the load off of oem components and wiring. My only complaint for these are they aren’t quite wide enough for pickup trucks. I made them work without modification but they’re tight. They handle my led lights great and at night it’s nice and bright now. Harness quality is good.

This harness fits 2005 Chevy Astro van
I have a 2005 Chevy Astro cargo van, this installed in it perfectly. It did take about an hour and I had to pull the windshield washer reservoir to get to the ground point by the passenger side headlight. But there are ground points on both the driver side and passenger side, no new ground points have to be drilled. I was also able to connect the hot wire directly to the upfitters circuit on the fuse box, the two red wires going to the front that are bolted to studs. I did use a self-tapping screw to attach one of the relays to the front of the vehicle under the hood. This is a very effective way to convert an Astro van with switched grounds into a modern LED headlight vehicle.I paired this with a set of “UNI-SHINE 5×7 led headlight 2pcs 7×6 led headlight H6054 H5054” and it worked out of the box. I did not have to repin or use an adapter to connect them, they just went straight into the plugs provided after wiring the harness. Headlights work as expected, daytime running lights come on as before, daylight sensor works as expected, and obviously high beam low beams work great.

GREAT PRODUCT, KNOW YOUR APPLICATION
This wire/relay “kit” is made well enough and will serve it’s purpose well BUT be certain that your application uses negative grounding as mentioned in the WARNING. I could not use a negative ground circuit, subeauently, to usd this harness I needed to take it appart and rewire the relays for my apllication specific…MY FAULT. The components are decent wuality and the construction is sound.

Easy to connect and high quality
Absolute quality. Very easy to connect. I used this on a 1996 Tacoma that I was adding LED headlights to. This harness was very easy to connect. It worked perfectly with the Tacoma negative applied polarity to the headlights. The LED headlights require a positive applied polarity. The harness was super easy to connect. My son and I got it connected in less that one hour. Quality plugs. Would absolutely recommend.

Plug & play mod for H4 headlights, it has increased brightness and flash response time by a big margin. It’s a one-time investment to tune up poor headlights. Make sure you place the relays in a good place away from direct heat.

The connectors and wiring are good quality, and the wiring diagram was easy to understand. Hooked it up, and worked immediately for converting my 1991 Toyota MR2 to LED lights. Thank you.
